The Challenge

Problem & Constraints

Legacy analytics tools loaded 150KB+ tracking scripts, required invasive consent banners, and suffered from 4-second dashboard load times that frustrated enterprise operations teams.

The Solution

Architectural Approach

Built a custom privacy-friendly telemetry engine with salted hash IP anonymization and Next.js React Server Components. Aggregated charts render on the server and stream to clients with zero client-side charting libraries.

Key Architectural Decisions

Eliminated client-side charting libraries (saved 280KB bundle size) by generating pure SVG markup on the server.
Used salted cryptographic hashes for IP storage to guarantee zero personally identifiable information is stored.
Employed streaming React Server Components to render the app shell instantly while historical data resolves.

Server-Authoritative Rendering

Reducing bundle weight while preserving interactivity

Traditional web dashboards ship megabytes of client graphing libraries. Pulse computes SVG coordinate paths directly on the server, streaming lightweight SVG markup with inline data attributes.

Client interaction is limited to a lightweight hover tooltip component under 3KB.

Key Takeaways

✓First Load JS dropped from 320KB to 42KB.
✓Sub-100ms dashboard paint on 3G network connections.
